CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation application of prior application Ser. No. 14/632,495, filed on Feb. 26, 2015, which was based on and claimed priority under 35 U.S.C. § 119(a) of an Indian patent application filed on Mar. 4, 2014 in the Indian Intellectual Property Office and assigned Serial number 1091/CHE/2014, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to an image capturing device. More particularly, the present disclosure relates to improving results of image composition and providing an indication to capture missing portions to a user while capturing the image.

BACKGROUND

With the advent of relatively inexpensive image and video capturing devices, such as cameras, or integrated devices, such as still/video camera features of mobile phones, and the like, there has been a greater expectation of being able to take images and videos at many more locations. Implementing an automatic optimal zoom for capturing an image is a significant consideration for a designer and a manufacturer of a contemporary image capturing device. With the automatic optimal zoom feature in the image capturing device, even an amateur understands some aspects of photography.

Image capturing devices of the related art consider a foreground region and a background region, such as a prominent building, a landscape, and the like, while capturing the image and automatically zoom in on a region of interest. In automatic zoom enabled image capturing devices of the related art, a user of the image capturing device needs to manually identify a missing region in a field of view of the image capturing device and adjust the image capturing device to capture the missing region while capturing the image. For example, when a prominent building is present behind a region of interest, then the user needs to manually identify the prominent building and adjust the image capturing device to capture the prominent building along with the region of interest.

In another example of the related art, when a person is selected as the region of interest and a portion of a face is missing in the field of view, the user has to manually identify the missing face and adjust the image capturing device to include the missing face while capturing the image.

The major shortcoming of the method of the related art is that the automatic zoom provided by the image capturing device does not recommend the user to capture missing portions or regions in the field of view while capturing the image.

Therefore, a need exists for improving results of image composition and providing an indication to capture missing portions to a user while capturing the image.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by a personal having ordinary skill in the art to which this disclosure belongs.

Proposed image: Image that is not captured by an image capturing device, however visible through lens and displayed in a view finder.

Image capturing boundary: Refers to a region before the lens of the image capturing device which may include one or more Region of Interest (ROIs). If the ROI is not selected, then the entire field of view of the image capturing device is selected as image capturing boundary.

Composition measure: Refers to an independent value for some characteristic of the proposed image and provide an indication that might not be optimal for one characteristic versus another characteristic. The image capturing device might provide guides on a viewfinder to, for example, divide the image into a three-by-three array so that the user can position one or more subjects at one of the corners formed by that array (i.e., follow the “rule of thirds”).

Guard space: Refers to a boundary space considered around a selected ROI), which is maintained as a constant space while computing the optimal zooming level.

The various embodiments herein achieve a method and system to optimize an image capturing boundary in a proposed image. An image capturing device captures the proposed image and a user view the proposed image through a view finder. The method includes locating an image capturing boundary in the proposed image. Further, the method includes computing composition measure for the image capturing boundary. For example, the image capturing boundary can include one or more ROIs. For example, the ROI includes, but is not limited to, a foreground object, a background object, a moving object, and any prominent object in the field of view of the image capturing device. The method includes identifying one or more missing portions in the image capturing boundary based on the composition measure. For example, the method detects the prominent building automatically and identifies the missing portions of the building in the field of view of the image capturing device. Further, the missing portions can be identified by comparing other images of the same building with the image in the field of view. In an embodiment of the present disclosure, the prominent building can be detected by using suitable techniques, such as, but is not limited to a Global Positioning System (GPS). In an embodiment of the present disclosure, other images of the detected prominent building can be obtained from a cloud. Further, the method includes providing an indication to the user. For example, the method provides suggestions to the user to change the orientation of the image capturing device to capture the one or more missing portions.

For example, the method may provide graphical indications, such as arrows, and the like, and/or verbal suggestions in the field of view alerting the user to capture the missing portion. Furthermore, the method analyzes one or more objects being selected by the user and provides the parameters for computing the automatic optimal zoom level. Furthermore, the method computes automatic optimal zoom level in response to the actions performed by the user on the image capturing device based on the provided indication. Further, the method includes capturing the image by applying the computed automatic optimal zoom level in the image capturing device.

Unlike systems of the related art, the method provides automated optimal zoom level by suggesting the user to capture the missing portions or regions in the field of view while capturing the image. Thus, the method enhances the user experience while capturing the image by providing the automated zoom level with the recommendations instantly.

In an embodiment of the present disclosure, a user can select or deselect ROI in the field of view of the image capturing device by performing a gesture around the required region.

In an embodiment of the present disclosure, the gesture can be at least one of a tap gesture, a swipe gesture, a scroll gesture, and a hover gesture, a gaze, selecting one or more objects using a physical button in the image capturing device.

In an embodiment of the present disclosure, if none of region is selected as ROI, the method includes identifying missing portions in the entire field of view of the image capturing device.

In an embodiment of the present disclosure, the missing portion in the field of view can be the foreground object, the background object, the moving object, the prominent object, a threshold space for the object, a positioning of object, and the like.

In an embodiment of the present disclosure, if none of the objects are selected in the image capturing device, the method sets the optimal zooming level by considering all the objects displayed within the field of view of the image capturing device.

In an embodiment of the present disclosure, an image capturing device includes, but is not limited to, a digital camera, mobile phone, smart phone, tablet, Personal Digital Assistant (PDA), or any electronic device capable of capturing the image.

In an embodiment of the present disclosure, the parameters related to the selected one or more objects can be the foreground object in the field of view, the background object in the field of view, the moving object in the field of view, the prominent object in the field of view, a threshold space for the object, a positioning of object in the field of view, and the like.

Referring now to the drawings, and more particularly to FIGS. 1 through 11, where similar reference characters denote corresponding features consistently throughout the figures, various embodiments of the present disclosure are presented.

FIG. 1 illustrates a plurality of modules in an image capturing device to optimize an image capturing boundary in a proposed image according to various embodiments of the present disclosure.

The image capturing device 100 allows the user to select or deselect ROI from the proposed image before capturing the image.

In an embodiment of the present disclosure, the image capturing device 100 identifies the characteristics of the proposed image. In an embodiment of the present disclosure, characteristics can be a geographic location, a preference obtained from the user, ambient conditions (indoor/outdoor), and past actions of the user.

For example, the GPS module 104 in the image capturing device 100 is configured to identify the location of the proposed image. In another example, when a prominent object is present in the proposed image, then the GPS module 104 identifies the location of the prominent building.

In an embodiment of the present disclosure, the image capturing device 100 allows the user to select characteristics of the proposed image for computing an automatic optimal zooming level before capturing the image. For example, the characteristics of the proposed image can be, but is not limited to, a pre-configured mode, such as a group photo mode, an indoor mode, an outdoor mode, and the like.

The image capturing module 101 is configured to capture the proposed image in the field of view of the image capturing device 100.

The processing module 102 can be configured to locate the image capturing boundary in the proposed image. In an embodiment of the present disclosure, the image capturing boundary can include one or more ROIs. In an embodiment of the present disclosure, if there is no ROI, then the processing module 102 is configured to select the entire field of view as image capturing boundary. For example, the ROI can be, but is not limited to, a foreground object, a background object, a moving object, and any prominent object in the field of view of the image capturing device 100. Further, the processing module 102 can be configured to compute the optimal zoom level automatically based on a framing area of the objects present in the field of view.

In an embodiment of the present disclosure, the processing module 102 can be configured to compute the framing area based on parameters, such as, but is not limited to, a number of people, a mode of operation of the image capturing device 100 (indoor/outdoor), and the like.

In an embodiment of the present disclosure, the processing module 102 can be configured to compute the optimal zoom level automatically in response to the actions performed on the image capturing device 100.

In an embodiment of the present disclosure, if the user accepts the indications provided by the image capturing device 100, the processing module 102 can be configured to compute the automatic optimal zoom level by including the missing portions in the proposed image.

In an embodiment of the present disclosure, if the user rejects the indications provided by the image capturing device 100, the processing module 102 can be configured to compute the automatic optimal zoom level by excluding the missing portions in the proposed image.

In an embodiment of the present disclosure, the processing module 102 can be configured to provide the automatic optimal zoom level such that the image capturing boundary is positioned properly within the proposed image.

In an embodiment of the present disclosure, the processing module 102 can be configured to increase the zoom level of the image capturing device 100 by leaving guard space around the image capturing boundary.

Further, the processor module 102 can be configured to capture the proposed image with the computed automatic optimal zoom level.

The composition measurement module 103 can be configured to compute composition measure for the image capturing boundary.

In an embodiment of the present disclosure, composition measurement can be computed by the composition measurement module 103 by providing guides on a viewfinder to, divide the image capturing boundary into a three-by-three array and can determine position of one or more subjects at one of the corners formed by that array (rule of thirds). For example, the frame of the proposed image can be divided into thirds horizontally, a top third, a middle third and a bottom third. Further, the proposed image can be divided into thirds vertically, a left, a center and a right which creates a 3 by 3 grid. A stronger composition measurement can be done by placing the ROI on one or more of the lines created in the grid.

Furthermore, the composition measurement module 103 is configured to identify one or more missing portions in the image capturing boundary based on the composition measure. For example, the image capturing boundary includes faces. The composition measurement module 103 is configured to detect the faces automatically and identifies the missing portions of the faces in the field of view of the image capturing device 100. For example, the composition measurement module 103 detects the prominent building automatically and identifies the missing portions of the building in the field of view of the image capturing device 100. Further, the missing portions can be identified by comparing the proposed image with other images of the same prominent building.

In an embodiment of the present disclosure, the prominent building can be detected by using suitable techniques, such as, but is not limited to, a GPS. In an embodiment of the present disclosure, other images of the detected prominent building can be obtained from a cloud storage/database. In that case, the image capturing device 100 communicates with the cloud storage using a communication interface module.

In an embodiment of the present disclosure, the other images of the prominent building can be obtained from the storage module 106.

The indication module 105 is configured to provide an indication to the user associated with the image capturing device 100 wherein the indication is to optimize the image capturing boundary based on identified at least one missing portion. For example, the indication module 105 is configured to provide graphical indications (e.g., arrows) in the about the missing portion in the proposed image. In an embodiment of the present disclosure, the indications include providing suggestions, such as a visual, an audio, a tactile display, and the like, that can be displayed in the proposed image about the missing portion in the proposed image. For example, the image capturing device 100 may suggest the user: to tilt the image capturing device 100 upwards or downwards, to move the user forward or backward to the ROI, to move the image capturing device 100 away from the ROI, and the like. In an embodiment of the present disclosure, the visual suggestion can be directional to optimize the image capturing boundary. In an embodiment of the present disclosure, the indication module 105 can be configured to determine whether the user has accepted the indications provided to capture the missing portion in the proposed image.

The storage module 106 can be configured to pre-store the images of the prominent buildings and a captured image.
